Maximum units per day (MUE)

Medicare’s Medically Unlikely Edit caps this code at 3 units per patient per day — Date of Service Edit: Clinical. Units above the MUE are denied; some MUEs can be exceeded only with appropriate documentation and modifiers where policy allows.

How the amount is calculated

The Medicare PFS amount is built from three Relative Value Units (RVUs) — work, practice expense, and malpractice — assigned to this procedure code. Each RVU component is adjusted by Geographic Practice Cost Indices (GPCIs) specific to the locality where the service is furnished, then the adjusted RVUs are summed and multiplied by the annual national conversion factor. Because practice-expense RVUs differ depending on whether the service is performed in a non-facility (e.g., office) or facility (e.g., hospital) setting, the resulting allowed amount is typically higher in the non-facility setting. The conversion factor is updated annually by CMS and applies uniformly across all codes before locality adjustments.

RVUs — work 1.75, practice expense 9.07 (non-facility) / 2.17 (facility), malpractice 0.27 — × the locality GPCIs × the 2026 conversion factor of $33.40.

Good to know

All figures are estimates based on the national unadjusted PFS calculation; actual payment depends on the specific locality's GPCIs.
Medicare typically pays 80% of the allowed amount after the patient meets the annual Part B deductible; the remaining 20% is patient or secondary-payer responsibility.
Modifiers, multiple-procedure reductions, sequestration, and annual budget-neutrality adjustments can change the final payment.
Always verify current rates and locality-specific amounts with your Medicare Administrative Contractor (MAC) before billing.

Frequently asked

Why is the facility amount lower than the non-facility amount?

In the facility setting, Medicare assumes the facility (e.g., hospital) incurs certain practice-expense costs, so the practice-expense RVU assigned to the physician's service is lower, reducing the total RVUs and the resulting payment.

Does this amount reflect what my practice will actually be paid?

No. This is a national estimate before locality adjustment. Actual payment depends on the GPCIs for your specific Medicare locality, any applicable modifiers, and current claims processing rules.

Why might the amount change during the year?

CMS can apply mid-year adjustments such as sequestration, and the conversion factor and RVUs are revised annually, sometimes with retroactive budget-neutrality corrections.

What percentage of this amount does Medicare pay?

Generally Medicare pays 80% of the allowed amount once the Part B deductible has been met; the remaining 20% is the beneficiary's or secondary insurer's responsibility.
